This study evaluated structural safety of ammunition elevator door for naval vessel by computational aided engineering. First, an initial model that satisfies classification regulations was performed static structural analysis under the hydrostatic loads. As an analysis result, structural vulnerability of an initial model was identified, so a stiffener’s volume was selected as an design variables and progressed design reinforcement. The stiffener was reselected based on material cost and strength, and evaluated structural safety of a design reinforced model.

In this research, design reinforcement and structural stability evaluation of a telescopic bridge are introduced which is used for transferring people and supplies safely between OSV and offshore plants. Analysis cases were selected considering classification rules(DNV-GL) and computational analyses were performed. According to the analysis result, researched proper design reinforcement by checking weak parts and tried to reinforce design effectively.

A knock out drum is a type of pressure vessel, which is one of the facilities for the safe treatment of residual gas, and serves to pre-separate droplets and other particles from flowing into the gas exhaust/combustion system. Knockout drums are operated under high temperature and high pressure operating conditions, so it is essential to design a knockout drum that reflects these conditions. This study intends to propose a method for designing and evaluating a knockout drum that satisfies both structural stability and droplet removal performance. Accordingly, for the purpose of design with structural safety, FEM structural analysis and evaluation methods based on ASME code are presented. And to evaluate the droplet removal performance of knockout drum, a case of applying particle tracking method using CFD is presented.
